regression: radeon DRI and SMP is bad

Created an attachment (id=2207)
My xorg.conf

I haven't touched my xorg.conf, I assume it was generated when I upgraded to
Hoary.

johan@transwarp:~$ dpkg -l xserver-xorg

Any chance you could give this a go with breezy?

If there's a live CD for Breezy with SMP kernels on it, yes, otherwise no. Are
there any of those? The Hoary live CD had only non-SMP kernels.

This is my workstation at work, so I really don't want to mess around with it
too much. A live CD would be peachy though.

Not yet, unfortunately, but thanks for following up. :) If you could give this a
shot when it's more convenient for you, that would be fantastic. Thanks.

I'll try this out either when an SMP Live CD comes out (bug 12622), or shortly
after Breezy is released.

If you can't test this before the release, we won't be able to fix it. Can you
install Breezy on a second partition for testing purposes?

I'm sorry, no.

I realize this means you won't be able to do anything about it, at least before
release. That's unforturnate, but this isn't anything I can put too much time into.

I'll let you know what happened after I upgrade to Breezy, or when the SMP live
CD comes out, whichever comes first.

Unfortunately, if we need to wait 6 months for you to test a new package, it is
unlikely that this bug will be fixed in less than one year. Lowering severity
since it can't be confirmed in recent code.

I have the same graphic card:

0000:01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY
[Radeon 7000/VE]

On an Hyper-Threading P4. If I boot an SMP kernel, the system freezes about 30
seconds after I login an X Session, but it is perfectly stable with a non-smp
kernel.

I have this problem in Hoary *and* in the latest Breezy (tried yesterday).

I am using the 'ati' X driver. I will try the fglrx one and give some feedback
later.

When loading the fglrx kernel module, I get the following error:

No device found!

So I have been unable to test X with the fglrx driver instead of the ati one. I
did took the time to put the SMP kernel under some stress using cpuburn and it
seemed very stable, as long as X was not running.

I have the same problem and I'm using Breezy. Whenever I use the smp kernel in
combination of my Radeon 7000 card the system gets completely frozen. If I
disable "dri" in my xorg.conf then everything is ok (except that I don't have
any 3d acceleration, of course). This is a common bug and I found a reference to
it here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=152648

I hope this can be fixed for Breezy.

... and here there is more information about it that might be helpful, a little
bit outdated though.

Thanks for testing.

That's unlikely unless the fix is extremely simple and obvious. Ubuntu 5.10
releases in just a few days, and there is no time to regression test non-obvious
fixes.

...well, whatever time it takes I'm willing to help. Just let me know what can I
do to contribute make things clear for you (e.g. testing, sending logs, etc). On
my side I'll keep trying to find what is this about.

thanks!

I found a discussion about this bug including some patches:

we'll pick this one up when we get the new ati driver in dapper

I'm not sure what that means exactly, but since Dapper is out and that was almost a year ago, I'm changing status from Rejected -> Unconfirmed, hoping for re-triage.

This is a regression from Warty.

I'm using Dapperdrake with
kernel 2.6.15-23-686 with SMP.
X Window System Version 7.0.0
ATI Radeon RV100 QY [Radeon 7000/VE]

System freezes when dri is enabled in xorg.conf (as described in this bug)
It seems like this bug is rv100-specific.

Please reopen.

https://bugs.freedesktop.org/show_bug.cgi?id=5111
also describes this bug.

Is this still an issue on Feisty?

During the almost two years since I first reported this problem I've replaced my hardware, so that ATI card is no more with me. Sorry, cannot answer the question.

Some of the other people on this bug might though?

Steven : seems it is still an issue in Feisty See: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/114520

Nope, that bug is for another model, this one was about rv100 and it should be fixed long ago.
